Wood Plastic Composites are developing rapidly in recent years and
having a fast market growth. Such products can include recycled polymers
and fibers as material ingredients. Currently, the majority of the
product shapes are limited to simple deck profiles. For geometries that
are relatively complex, expensive injection molding is the most commonly
used method of manufacturing. The injection molding requires high
pressures and demands complex tool arrangements. With press forming
method, the forming pressure and the length of press cycle can be
reduced with a simpler and less expensive toolset. This article
investigates the effect of press forming force of thermoplastic in WPC
granules pressed into ASTM D638 tensile dog-bone shaped specimens.
Tensile strength, modulus of elasticity and yield point of the created
samples are tested according to the standard and compared to the
commercially available materials. In addition, the surface quality for
each of the samples is measured using a 3D profilometric device. From
the results, it can be determined that the press forming method is a
capable way to produce complex geometries with fewer demands for the
